It is notable that the non-type, NMMB-P21741 (199+ mm TL), has a total 144+ vertebrae. However, the tip of tail is quite tapering and does not look damaged, or at most only few rear vertebrae lost. The tail length is 64.3% TL, not much different from these congeners with complete filiform tails. The coloration on body surface is mostly faded and the most parts of vertical fins are pale, except for the posterior portion. The peritoneum is similar to that of

There is one row of scattered dots on the lateral body and some internal dots on the ventral side of the abdomen. It also has a slightly different vomerine tooth pattern (
